These two lectures explore how time is modeled in theoretical analyses of individual industries and of the entire economy. The atemporal Marshallian model is contrasted with an explicit time model with uncertainty about costs at the firm level. The book also examines data on job creation and job destruction; price setting behavior in monopolistic competition and costly search models; data on price changes; and both cyclical and seasonal data on the entire economy. With a focus on the command over purchasing power, the Arrow-Debreu and Hicksian ISLM models are compared with a number of...

Providing a comprehensive introduction to modern auction theory and its important new applications, this book is written by a leading economic theorist whose suggestions guided the creation of the new spectrum auction designs. Aimed at graduate students and professionals in economics, the volume provides the most up-to-date analysis of traditional theories of "optimal auctions" as well as newer theories of multi-unit auctions and package auctions, and shows by example how these theories are used. It explores the limitations of prominent older designs, such as the Vickrey auction design, and...
